Jury Deadlock Leaves Lindsay Clancy Murder Trial in Mistrial
9/10/2026, 4:17:05 AM
Core Event
In September 2026 a 12-person jury in Plymouth County Superior Court failed to reach a unanimous verdict on Lindsay Clancy’s responsibility for the strangulation deaths of her three children on January 24 2023. After more than 38 hours of deliberation over seven days, the panel reported an 11-1 split in favor of a not-guilty-by-reason-of-insanity verdict. The lone male juror cited “reasonable doubt” but refused to vote for the insanity acquittal, prompting Judge William Sullivan to declare a mistrial on September 4 2026.
Background & Context
Clancy, a former labor-and-delivery nurse, has never denied killing her 5-year-old daughter Cora, 3-year-old son Dawson, and 8-month-old son Callan. Her defense argued she was experiencing postpartum psychosis, a rare condition that can involve hallucinations and loss of reality. Under Massachusetts law, jurors must find the defendant understood the wrongfulness of her actions to convict; reasonable doubt about criminal responsibility requires a not-guilty-by-reason-of-insanity verdict. Prosecutors maintained that Clancy planned the killings and acted with awareness, seeking convictions on three counts of first-degree murder.
Data & Statistics
- Deliberation time: ? 38 hours over seven days.
- Jury composition: nine women, three men.
- Verdict split: eleven jurors favored a not-guilty-by-reason-of-insanity verdict; one opposed.
- Charges: three counts of first-degree murder; potential life-without-parole sentence if convicted.
Official Statements & Responses
District Attorney Tim Cruz said, “This was, and always has been, about getting justice for those three little babies.” The judge reiterated the legal standard for reasonable doubt and refused a defense request to remove the holdout juror. Defense attorney Keith Halpern warned that future jurors would face intensive questioning about social-media exposure. Clancy’s lawyer Kevin Reddington plans to move for dismissal on double-jeopardy grounds at the upcoming status hearing.
Criticism & Opposition
Jurors who spoke publicly described the holdout juror as “very arrogant” and said he disregarded expert testimony from fellow jurors who were nurses. Several jurors also criticized the prosecution’s approach as “harsh” and lacking character witnesses that could have contextualized Clancy’s mental state.

Conflicting Reports & Gaps
Sources uniformly report an 11-1 split, but the holdout juror’s reasoning remains undocumented; he has not spoken publicly, and the court record does not reveal his written statements. While jurors repeatedly mentioned “reasonable doubt,” the exact legal rationale the juror used to reject the insanity verdict is not detailed in the public record.
What’s Next
A status hearing is scheduled for September 29 2026. Prosecutors will decide whether to seek a retrial, pursue a plea agreement, or drop the case. Defense counsel intends to file a motion to dismiss on double-jeopardy grounds, arguing that the mistrial lacked “manifest necessity.” The outcome will determine whether Clancy remains in the state psychiatric hospital pending further proceedings or faces a new trial.
